Product Description
The RF1604 is a single-pole four-throw (SP4T) switch designed for general
purpose switching applications which require very low insertion loss and
high power handling capability with minimal DC power consumption. The
excellent linearity performance achieved by the RF1604 make it ideal for
use in multimode GSM/EDGE/WCDMA, LTE, and cellular infrastructure
applications. The RF1604 offers very high isolation between the RF ports,
providing greater RF separation between the transmit and receive paths,
which is critical in full-duplex systems. Additionally, RF1604 includes inte-
grated decoding logic, allowing just two control lines needed for switch
control. The RF1604 is packaged in a very compact 2.5mmx2.5mm, 12-
pin, leadless QFN package.

Control Logic
The switch is operable in four states (see Truth Table). When VDD is high, the switch is active. The start-up time is defined as
the delay time that control signal(s) cross 0.8V threshold until KF output level is 90% of final RF voltage peak.
Power Sequence
ON Sequence: First turn ON VDD, then apply control signals.
OFF Sequence: First turn OFF the control signals, then turn OFF VDD.
Note:
Not following the power ON/OFF sequence could cause damage to the switch and may affect the long-term reliability of the
device.
Electrical Test Methods
The electrical parameters for the switch were measured on RFMD evaluation board. The test PWB includes means for decou-
pling RF signals from control signal port (shunt capacitor at control signal ports).
All measurements are done with calibration plane at switch pins. The effect of test board losses and phase delay has been
removed from the results.
